Have visited forum many time to help in repair issues. I have encountered a problem that I have not seen posted before - 2001 e39. The passenger seat was moved rearward and will now not move forward. I can remove the seat because it is stuck in the rear position with the seat over the bolt. I have determined that the switch module works -checked continuity. So I believe that something is either jamming the rail or the motor is no longer working. I think I would be able to diagnose the problem if I could get the seat out. Any ideas?
